An FL-PID mixed technique to control a military rocket launcher system board

This article proposes the design and construction of an automatic launcher system for military weaponry. combining the fuzzy-logic and proportional-integral-differential control theories,the launcher system board is purposed to automatically direct a military rocket along its azimuth and elevation angles direction. the fuzzy-logic method has been explored to find the values of kp,ki and kd constants of a proportional-integral-differential controller,which will then be used to adjust the angular position of actuator according to a predetermined set-point. the combined control algorithm has been implanted on the arduino mega 2560 and implemented to launch the 70 mm-caliber rolex rocket being considered during the experiment. successful control result,which was indicated with the average steady-state error value of 0%,has been resulted.
